Thanks for the wonderful Bikeman, many people have wanted the download link for the specific ReShade version needed for Squad. So here is a spare download link in case the main link is unusable.
When installing it, point it towards your Squad Installation. Use the following directory: “\Program Files (x86)\Steam\steamapps\common\Squad\Squad\Binaries\Win64\Squad.exe”
Once you have it downloaded/installed, you can get the ReShade config files for Squad at ferrius.eu/reshade/ there should be installation instructions there.
Hopefully this will last. If there is any issues, message me on Twitter
